Board adapts embedded systems to their
environment
A novel environmental fan card provides temperature-controlled forced-air cooling together with environmental monitoring of humidity and pressure conditions for PC/104 computer systems.
The ThermoCool II PC/104 environmental fan card is a multifunction addon module for PC/104 computer systems that provides temperature-controlled forced-air cooling together with environmental monitoring of humidity and pressure conditions Pricing ranges from $187 to $224 each in volume orders of 100+ units, depending on configuration

Fingerprint board isn't fooled by phoney fingers
Parvus Corp is developing modular fingerprint identification hardware for embedded computer applications in co-operation with Fujitsu Microelectronics America (FMA).
The board's two high-efficiency brushless fans are designed to turn on and off in reponse to changing temperature conditions, while conserving power and increasing product life when not in use.
In a sealed enclosure, the environmental fan card can effectively reduce or even eliminate the need for an embedded system to have outside air exchange.
Air is driven in a push-pull circular cooling pattern around the fan module and adjacent PC/104 cards.
Besides providing thermal management, the environmental fan card integrates capacitive humidity and atmospheric pressure sensors, which can be used as alarm indicators of moisture and pressure changes within an enclosed PC/104 system.
The humidity sensor measures from 1-99% relative humidity with instantaneous desaturation, and the board's pressure sensor delivers a highly accurate, linear voltage output directly proportional to applied pressure (0-200kPa) - with precise span and offset calibration, as well as temperature compensation.
This product is available in two versions - one with all three sensors (temperature, pressure, humidity) and another with a temperature sensor only.
Standard features include two Form C relays, two digital inputs, four or seven analogue inputs, LED indicator, configuration jumpers, and Windows 9x/NT/2000/XP drivers and test utility.
An optional cable set with an external digital temperature sensor is also available if remote fan management is desired.
